98S55005000000 is a specialized aerospace engine lubrication system pressure testing tool, compliant with AS9100D quality standards and FAA/EASA MRO regulations, designed for CFM56 and IAE V2500 turbofan engines. It is used to verify the pressure tightness of the engine lubrication system during maintenance, detecting leaks, blockages, or pressure anomalies that could cause insufficient oil supply, component overheating, or premature wear of rotating engine parts.

Made from high-strength stainless steel with a corrosion-resistant finish, it features precision pressure sensors and adjustable pressure regulation structures, operating stably in -20°C to 70°C workshop environments. Weighing 1.02kg with a quick-connect fitting design, it streamlines testing workflows and ensures pressure measurement accuracy within 0.5 psi. It is an essential tool for lubrication system MRO work.
